Rei Saiga

Rei Saiga (斎賀 玲), also known as Psyger-0 (サイガー0, Saigā Zero).

One of Shangri-La’s top players. She earned the title “Maximum Firepower” by achieving the highest burst damage in the game. Her in-game avatar is a man covered head-to-toe in legendary equipment, but in the real world she’s a pretty teenage girl who has a crush on Sunraku.
